Description

  The present invention mainly relates to a shower head used in a bathroom.

  This type of shower head is formed of a synthetic resin in which main components are molded in order to obtain manufacturability and ease of handling during shower use. Some external parts made of synthetic resin are plated with metal. By forming the main component parts from the molded synthetic resin, the component parts can be easily manufactured by injection molding, the shower head becomes light, easy to hold, and hot water is difficult to cool. Further, the appearance of the shower head is improved by applying metal plating to the outside of the component.

  However, the metal plating for the component made of synthetic resin is formed by immersing the component in a metal plating solution. Therefore, a plating layer is formed around the entire part. For this reason, in the case of a cylindrical part that forms a flow path for water or hot water, a plating layer is also formed on the inside, and when this inner plating layer is peeled off, the shower discharge hole is peeled off. May be blocked by

  In Patent Document 1, a shower head including an outer main body and an internal flow path member that forms a flow path inside the main body is disclosed. In such a shower head, appearance can be ensured by plating the outer body, and a shower discharge hole is blocked by peeling plating by using a member having no plating layer as an internal flow path member. It can prevent peeling.

JP 2001-128873 A

  However, in the configuration of Patent Document 1, the main body and the internal flow path forming member are fixed by a clip that is stopped from the outside of the main body. When the clip is provided in this way, the number of parts of the shower head increases, so that the configuration becomes complicated and the assembling work takes time. Moreover, since the clip and the hole for a clip are exposed outside, an external appearance property falls. For this reason, it is conceivable to provide a cover for concealing the exposed portion of the clip and the hole for the clip. However, if this is done, the number of parts will be further increased and the assembly work will be troublesome. In addition, the portion where the clip is mounted, for example, the gripping portion may swell or thicken to secure the mounting space for the clip. In such a case, the design of the shower head is degraded. .

  The present invention has been made paying attention to such problems existing in the prior art. The purpose is to provide a shower head that is excellent in appearance quality and design, can reduce the number of parts, and is easy to assemble.

  In order to achieve the above object, in the present invention, there is provided a housing having a head portion and a grip portion, and a shower discharge portion provided in the head portion, and a water or hot water flow path incorporated in the housing. A shower head including a flow path member to be formed is characterized in that the flow path member is positioned and fixed to the housing by surface contact with the housing.

  If comprised in this way, a flow-path member will be positioned and fixed with respect to a housing, without using components for fixation, such as a clip. Therefore, the number of parts is reduced, and it is possible to prevent the appearance quality and designability from being impaired.

Next, a method for assembling the shower head 11 configured as described above will be described.
As apparent from FIGS. 2 and 10, when assembling the shower head 11, the partition member 18 is inserted into the head portion 22 from the opening 23, and the connecting tube 49 is inserted into the grip portion 19. At this time, as shown in FIG. 10, the partition member 18 is displaced downward from the original built-in fixed position in the head portion 22 and is positioned in the enlarged diameter portion 26 of the opening 23, as shown in FIG. 7. The stopper 50 is spaced downward from the outer peripheral surface of the female screw cylinder 25A indicated by a two-dot chain line. Further, as shown in FIG. 10, the flat surface 62 of the inner pipe 21 is separated from the flat surface 59 of the grip portion 19 to the lower side outside the grip portion 19 at this displacement position.

  On the other hand, the inner pipe 21 is inserted from the lower end opening of the grip portion 19, and the upper male screw 54 is screwed into the female screw 55 of the connecting pipe 49 of the partition member 18. At this time, since the partition member 18 is displaced downward from the built-in fixed position in the opening 23, the flange 61 of the inner pipe 21 is exposed to the outside below the grip portion 19. Therefore, in this state, the inner pipe 21 can be connected to the connecting pipe 49 by screwing the male screw 54 of the inner pipe 21 into the female screw 55 of the connecting pipe 49 until the projections 56 and 57 come into contact with each other. In this way, the flat surface 62 at the lower end of the inner pipe 21 is vertically opposed to the flat surface 59 at the lower end of the grip portion 19 below.

  Next, the partition member 18 connected to the inner pipe 21 is moved upward in the opening 23, and as shown in FIG. 7, the stopper 50 is brought into contact with the lower part of the outer peripheral surface of the female screw cylinder 25B indicated by the solid line.

  (3) Since it is not necessary to secure a mounting space for pins, clips, etc., the shower head 11 is not formed with a bulging portion for mounting pins, clips, etc., and the design of the shower head 11 Can be prevented from decreasing.

(4) Since the rotation preventing portion of the inner pipe 21 is the flat surfaces 59 and 62 formed on both the inner pipe 21 and the grip portion 19, the configuration is simple.
(5) The partition member 18 constituting the flow path member is movable from the built-in fixed position to the displacement position, and the plane 62 of the inner pipe 21 connected to the partition member 18 at the displacement position is the plane of the grip portion 19. 59. Therefore, the inner pipe 21 can be rotated, and the inner pipe 21 can be connected to the partition member 18 without hindrance.

  (6) When the inner pipe 21 reaches a predetermined assembly position with respect to the partition member 18 in a state where the lower end of the inner pipe 21 is displaced downward from the lower end of the grip portion 19, the partition member 18 and the inner pipe 21 The protrusions 56 and 57 come into contact with each other to define the positional relationship between the partition member 18 and the inner pipe 21, and the plane 62 of the inner pipe 21 is disposed at a position corresponding to the plane 59 of the grip portion 19. Therefore, in this state, if the partition member 18 and the inner pipe 21 are moved upward from the displacement position, the flat surfaces 59 and 62 come into contact with each other, and the inner pipe 21 and the partition member 18 are positioned at the built-in fixed position. Therefore, the partition member 18 and the inner pipe 21 can be easily positioned and fixed at the fixed positions.

  (7) Around the screw insertion hole 45 of the partition member 18, there is provided a stopper 50 capable of contacting the outer periphery of the female screw cylinder 25 of the head portion 22, and the partition member 18 is moved from the downward displacement position to the upper fixed position. When moved, the stopper 50 is regulated in position by the female screw cylinder 25. Therefore, the partition member 18 can be easily assembled to the head portion 22 with the screw 46 at this position.
